Letters Patent No. 114,181, dated April 25, 1871.

IMPROVEMENT IN STOVE-PIPE CLEANERS.

The Schedule referred to in these Letters Patent and making part of the same.

Nature and Objects of the Intention..

The invention relates to that class of stove-pipe cleaners which consists in providing a stove-pipeJ withv a concavoconvexv disk, intended to .be drawn or forced toward or from the iue,.or up or down inthe pipe by means of an attachable and detachable rod, the convexity of the disk conforming to the concavity of the pipe, against which it is secured at the el,- bow by arigidly-attached standard passing through and fitting snugly in a small aperture in the pipe diretly opposite the center of the disk, it being provided outside of the pipe with a hole and pin, to secure thev disk in place when not in use.

Theextremity of that part of the standard outside of the pipe has a threaded cavity, into which the rod is screwed.

The chimney end of the pipe has a wire stretched across its diameter, to prevent the egress of the disk when forced in that direction.

AY section on one side of the same end of the pipe is removed, to allow draught when the disk is permitted to remain at that end of the pipe.

Description of the Accompanying Drawing.

Figure 1 is a perspective view of the disk A and standard B. l p

Figure2 is a view of the shaft O,joint D, and threaded sleeve E.

Figure 3 is a vertical longitudinal section through the stove-pipe, and the invention placed therein.

Figure 4 is an end view of the pipe, showing the method of seeming the disk when not employed.

Figure 5 is a vertical central section of shaft O, standard B, and disk A, showing the disk provided with the flanges L.

General Description.

A in the accompanying drawing is a concavo-convex disk of metal or other suitable material, the convexity of which should conform to the concavity, and its diameter be nearly equal to that of the stovepipe F.

The disk is provided at its center with a standard projecting therefrom at light angles tothe tangentof its convexity.

This standard is secured to the concave face of the disk by a dat head or button, its opposite parts passing through and nicely tting in an aperture in the stove-pipe directly opposite the center of the disk, and is secured by a pin, so that the disk is held closely in contact with the pipe, thus preventing any interruption of the draught.

'lhe extremity of the standard B is provided with a threaded cavity, into which the male screw on the end of the shaft C or joint D fits.-

When it is desired to lengthen the shaft G the joint D may be attached to it by means of the threaded sleeve E.

By the invention, if intended to be used in the specitic manner illustrated in the drawing, a wire, I, should be stretched across the diameter of the .upper or chimney end of the pipe, so as to prevent the disk Operation.

The stove-pipe is provided with an aperture of n proper size at 'a point directly opposite the axis of that portion of pipel opposite, through which aperture the standard B is passed, and when the inventiop is not in use the pin I? is inserted in the holein the standard contiguous to the exterior of the pipe, thus holding` the disk A in close relation with-the concavit-y of the inside, and preventing any obstruction" to the draught of the stove.

\Vhen it is desired to clean the pipe, it having been properly secured to the stove and so inserted in the chimney-flue as that the section H is whollyr therein,

the disk A being properly placed, attach the shaft C by screwing it into the cavity in the extremity ofthe standard B, or, if more length of movement be required, connect the joint D by means of the threaded sleeve E; then force the disk upward or forward, according as the invention is constructed to operate vertically or horizontally, whereby the soot is detached from the inside ofthe pipe and pressed into the chimney.

When it is preferred to draw the soot into the stove or down the pipe, the disk may be allowed to remain in contactwitb the wire I, any suitable attachment being affixed to that partrof the sha-ft() outside of the pipe to sustain it. This attachment beingr removed,

the disk Amay be drawn down or' forward, thus clean ing the pipe by a reverse movement from that above indicated.

Claims: What I claimA as my invention, and desire to secure 1. The combination of the extension-rod, composed ofthe shaft C, joint D, and threaded sleeve E, with the concavo-ccnvex disk B, provided with the stand-l 3. A stove-pipe provided with the cleaner herein described, when a transverse section of the chimney pipe provided with a wire passed across its opening, as shown, and for the purposes described.

In testimony that-l claim the foregoing improvements in stove pipe cleaners as. above described I have hereunto set vmy hand and seal this '1st dav'of February, 1871.V Y
